Removed Tab(role: .search) — it was always visible on all tabs. Now the floating action button changes based on selected tab: - Home/Fitness: FAB (+) → opens food assistant (same as before) - Reader: Play/Pause circle → toggles auto-scroll - Idle: play.fill icon, warm accent background - Playing: pause.fill icon, red background - Tapping toggles between play/pause Speed controls appear as glass capsule above the FAB when playing. Auto-scroll stops when switching away from Reader tab. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
